One would think it takes a supernova of a performer to launch fans as monomaniacal and strange as to be pegged as subjects for a documentary. But it doesn’t. At least, not in the case of Tiffany Darwish and I Think We’re Alone Now, the film that documents her borderline stalker fans, each of which has their own shrine, and each of which has delusions that Tiffany is their destined mate. As sad as all of these other fan devotions are, it takes special kind of delusion to be obsessed with a celebrity who literally has a “Career Stall” category on Wikipedia.
